Deere Unveils New 700L and 750L Dozers With Extra Energy and Extra Visibility in Bigger, Redesigned Cab (VIDEO)
John Deere has unveiled the following era of its 700-size-class dozers. After working carefully with the house owners and operators of the earlier era Ok-Collection to develop these new machines, the 700L and 750L dozers boast extra energy, extra consolation, extra visibility and refreshed electro-hydraulic controls.
The outcomes are a pair of dozers constructed to run all day whereas conserving operators comfy within the course of.
You’ll discover all the small print and photographs of the 700L and 750L in our newest video under. Or, in case you favor textual content, you’ll be able to learn the complete story after the break.
Deere product advertising supervisor for crawler dozers, Nathan Horstman tells us that these two dozers are primarily aimed toward web site improvement, street constructing and underground development functions.
“Among the largest issues our prospects are going to note about this 700L dozer is absolutely the ability of this machine. At 135 horsepower it’s nonetheless obtained the identical nice stability that the 700Ok had,” he says. “The subsequent factor they’re going to note once they get the seat of that machine, they’re going to note how massive and open and spacious the cab is and the nice visibility, throughout however particularly to the blade and ahead on the machine.”
The 700L and 750L are slated for launch in mid-June 2020.
Just like the Ok-Collection machines earlier than them, the 700L and 750L are powered by a 6.Eight-liter John Deere engine. Nevertheless, the brand new fashions function slight will increase in horsepower over the Ok-Collection. The 700L sees a 5-hp enhance to 135 hp whereas the 750L sees a 10-hp enhance to 175 hp.
“One of many issues prospects advised us is that we must always maintain the six-cylinder 6.Eight-liter engine. Whereas lots of the business has gone to a 4 cylinder engine, we’ve nonetheless obtained this bigger increased displacement engine. What that does for us is give us class main horsepower,” he says. “[The 700L] is 135 hp and that additional torque with that increased displacement engine lets the operator push by way of tougher materials, tougher spots once they’re grading.”
The 700L weighs in at a variety between 30,900 and 32,088 kilos. Deere has additionally elevated the working weight of the 750L by 750 kilos and the machine now weighs in at a variety between 37,569 and 40,zero40 kilos relying on the configuration you go for.
Deere says the elevated weight improves tractive effort on the 750L whereas additionally offering higher stability for an total enhance to the 750L’s efficiency.
Blade capability on the 700L ranges between 4.4 and 5.1 cubic yards whereas the 750L ranges between 5.2 and 6 cubic yards.
Deere can also be providing new, wider blade choices with these dozers, together with a 161-inch blade possibility on the 750L, which Deere says is the widest blade supplied on this measurement class. The 700L in the meantime options built-in spill sheets that additional enhance blade capability on that machine.
The 700L has Eight ft, 2 inches of monitor on the bottom whereas the 750L has 10 ft, 2 inches. Deere is providing three ranges of undercarriage on the 700 and 750L:
Heavy obligation sealed and lubricated monitor (SALT)
Prolonged life undercarriage
Max life undercarriage
“With the prolonged life undercarriage you get a really exhausting coating on the bushings and that offers us about 50 p.c extra life than a typical sealed and lubricated monitor,” Horstman says. “With Max Life you get that actually exhausting coating on the bushing however you additionally get bigger monitor hyperlinks. You get a bit of extra meat on the loafer, you get a bit of extra meat on the rollers—it is a seven curler undercarriage—and a bit of extra meat on the service rollers.”
Each fashions shall be accessible in XLT (additional lengthy monitor) or LGP (low floor strain) configurations.
Let’s transfer on to the cab of those dozers, which Deere calls a ground-up redesign.
With this new cab Deere says it was targeted on rising visibility and making the operator extra comfy. Horstman says the cab on these L-Collection dozers is 17 p.c bigger than the Ok-Collection fashions whereas providing door openings which can be 14 p.c bigger.
“We all know our operators spend extra time of their cab typically than they do at residence. So we positively needed to make it a pleasant place to be,” Horstman says. “We’ve obtained the brand new [optional] heated and ventilated seat…that heating possibility and a air flow possibility that’s going to tug air away from the operator and maintain them comfy all day.”
The brand new cabs may also be outfitted with optionally available computerized temperature management such as you’d discover a new pickup and a rear view digital camera.
Horstman says that rising visibility ahead and to the blade was an enormous focus for Deere within the design of the brand new cab.
“We opened up the scale of those home windows…the width of them are 16 p.c wider than they had been earlier than. That entrance window is wider, it’s taller,” Horstman explains. “If you happen to look to the aspect over the monitor, you’ll be able to see that you would be able to see the monitor. And those outdoors the monitor, we lowered these home windows down. Whereas we’re speaking concerning the home windows, one of many issues that we did is we truly went to pop-out home windows. The rationale we did that’s typically the sliding home windows are inclined to rattle. You are inclined to get silt within the backside of the slides they usually don’t work as properly over time.”
Plus, Horstman says Deere has achieved an enormous discount in noise on the 700L. “We decreased noise by 50 p.c and one of many issues that enables that’s these new viscous cab mounts,” he says.
Operators will even discover new electro-hydraulic controls in these L-Collection machines. “One of many massive enhancements on [the left side] is as an alternative of getting to maneuver the lever fore and aft, say to get in ahead and reverse, we truly simply have a rocker change right here,” Horstman says.
Whereas we had been testing the cab of the 700L at ConExpo, Horstman additionally confirmed us the revamped customized transmission settings that you’ve at your disposal in these new dozers.
“We’ve at all times had actually good management of our transmission. We’ve at all times given operators methods to tweak the best way the transmission acts and feels. One of many items of suggestions we obtained was it was a bit of bit difficult. So what we did is made transmission presets,” Horstman explains. “So we advocate for many operators to be within the regular setting. If you would like the machine to be a bit of snappier—extra aggressive—we’ve obtained a manufacturing setting and we have now a clean setting. Consider the sleek setting as sort of like a Cadillac. So the machine’s gonna roll out a bit of bit extra on reversals, it’s going to only really feel a bit of bit smoother, a bit of lazier.”
Deere has additionally put in a torque shift mode which mainly permits the 700 and 750L’s hydrostatic transmission to emulate the texture of a torque converter machine.
“If you happen to’re getting any person that’s popping out of a machine with a torque converter, that’s going to provide them a bit of bit increased increment gear shift, and make it really feel a bit of bit extra like a torque converter machine,” Horstman says.
“After which we’ve additionally obtained the customized menu and the customized menu basically has all of the stuff that the Deere dozers have at all times had when it comes to changes to the transmission. So you’ll be able to alter the aggressiveness of the tracks, the acceleration charge, the decel charge, the ahead and reverse charge, steer charge and pace in grip step measurement,” he provides.
The cab on these machines additionally contains a new 7-inch colour monitor that shows need-to-know operation information and grade management info.
“One other enchancment we made with this new 700L dozer is we truly raised up the grade management monitor not solely so you’ll be able to work together with it extra but in addition to get it in line of sight with the blade,” Horstman says. “So when the operator is wanting from the precise aspect to the left aspect of the blade, she or he can cross by way of and take a look at the grade management monitor.”
Grade management choices
Deere can also be providing a factory-installed entry degree grade management system referred to as slope management on these machines. Deere says this technique routinely maintains blade angle with out the necessity for an exterior laser or GPS reference. For novice operators, which means hitting grade extra precisely, whereas veteran operators ought to be capable to maintain grade with much less effort.
“Slope management basically permits an operator to enter a cross slope and a important fall angle and make a really primary slope or primary pad with out the necessity for GPS or GNSS satellite tv for pc protection or with out the necessity for like a laser elevation reference,” Horstman says.
When choosing slope management from the manufacturing unit, the machines additionally come SmartGrade-ready, do you have to wish to improve to Deere’s 3D mastless system sooner or later.
To extend uptime, these subsequent era dozers have optimized hydraulic hose and electrical harness routings to scale back the opportunity of rub factors.
“The engineers spent lots of time to ensure every hose and harness had its personal location to ensure it wasn’t rubbing towards something,” Horstman says. “All of the hoses are externally wrapped in a metallic spring. One other wrap across the hoses going to the blade. We even have a cable in there that in case you had been to get a department or one thing in there that will assist to maintain these hoses from getting ripped out.”
Moreover, hydraulic and hydrostatic oil change intervals are prolonged to 4,000 hours, lowering working value. That ought to prevent 13.5 p.c in fluid and filter prices over the lifetime of this machine.
Plus, the sheet metallic on the service doorways of the machines is 50 p.c thicker with improved sealing. Deere has additionally gone with an in-line DEF filter on these fashions for simpler substitute.
